Description

Technical Field

[0001] This utility model relates to the field of rail transit detection technology, and in particular to a rail height and low track electromagnetic adsorption measuring device based on laser string lines. Background Technology

[0002] Track elevation and alignment measurements can accurately capture track height and alignment deviations in real time, which is a core guarantee for the safe operation of rail transit. It can promptly detect potential hazards such as track settlement and lateral displacement, preventing train bumps and derailment risks during operation; it also provides data support for track maintenance, guiding precise adjustments and reducing maintenance blindness and costs; at the same time, it ensures smooth train operation, reduces wheel and rail wear, extends the lifespan of track and train components, and improves passenger comfort, which is of great significance to the safe, efficient, and economical operation of railway, urban rail, and other transportation systems.

[0003] The fixing of the track height and low rail measurement is achieved through the cooperation of a rotary switch, gear and shaft transmission, and a self-locking component. This quickly and stably fixes the laser lamp, ensuring a constant position of the laser reference beam and avoiding reference deviations caused by laser lamp offset during measurement. This provides a reliable reference benchmark for height and low rail deviation detection. Simultaneously, the self-locking structure achieves automatic locking via springs and limit blocks, eliminating the need for additional fixing steps, shortening measurement preparation time, and improving operational efficiency. Furthermore, the protective shell protects the self-locking component, reducing the impact of dust and impurities on the parts and ensuring long-term stable operation of the fixing mechanism. This indirectly guarantees the continuity and accuracy of track height and low rail measurement data, providing accurate data for subsequent track maintenance and adjustment.

[0004] In existing technologies, the measurement of track height and elevation relies on manual bolt fixing, which is cumbersome and time-consuming, making it difficult to quickly install and remove reference components. After fixing, the components are prone to loosening due to vibration, leading to reference offset and affecting measurement accuracy. The lack of an effective protective structure means that dust and rainwater can easily damage internal components, shortening their lifespan. Furthermore, the device has poor adaptability, making it difficult to be compatible with different specifications of laser lights, increasing measurement costs and operational complexity. To address these issues, a track height and elevation electromagnetic adsorption measuring device based on laser chords is proposed. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A track elevation and elevation electromagnetic adsorption measuring device based on laser string lines includes a support block, a track fixedly connected to the outer wall of the support block, a magnetic attraction mechanism slidably connected to the outer wall of the track, a fixing mechanism fixedly connected to the top of the magnetic attraction mechanism, a moving target slidably connected to the outer wall of the support block, and a target slidably connected to the outer wall of the support block.

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0011] Example: A laser-based electromagnetic adsorption measuring device for track 2 in high and low orbit directions, referring to... Figures 3 to 5The device includes a support block 1, which supports all components and ensures overall stability during measurement. The outer wall of the support block 1 is fixedly connected to a track 2, which provides a precise sliding path for the magnetic attraction mechanism 3, the moving target 5, and the target target 6. The outer wall of the track 2 is slidably connected to the magnetic attraction mechanism 3, which achieves a stable connection between the device and the track 2 through electromagnetic attraction, avoiding measurement displacement. The top of the magnetic attraction mechanism 3 is fixedly connected to a fixing mechanism 4, which is used to fix the laser lamp 36 and enable quick assembly and disassembly. The outer wall of the support block 1 is slidably connected to the moving target 5, which receives laser signals and provides feedback on deviations as the track 2 changes in height. The outer wall of the support block 1 is slidably connected to the target target 6, which serves as a reference to calculate the deviation value in conjunction with the moving target 5.

[0012] The fixing mechanism 4 includes a fixing block 41, which provides a mounting carrier for components such as the rotating component 42. The rotating component 42 is slidably connected inside the fixing block 41. The rotating component 42 drives the rotating rod 43 to move through the gear shaft transmission of the gear 421. The rotating rod 43 is slidably connected to the outer wall of the fixing block 41. The rotating rod 43 rotates along the fixing recess 44 under the limit of the rotating rod 45. The fixing recess 44 is fixedly connected to the outer wall of the fixing block 41. The fixing recess 44 provides space for the rotating rod 43 and transmits motion. The rotating rod 45 is fixedly connected inside the fixing recess 44. The rotating rod 45 limits the trajectory of the rotating rod 43. The self-locking component 46 is fixedly connected to the outer wall of the rotating rod 43. The self-locking component 46 achieves self-locking and prevents the laser lamp 36 from loosening through the spring 462 and the limit block 463. The protective shell 47 is fixedly connected to the outer wall of the fixing block 41. The protective shell 47 protects the self-locking component 46 from dust. The fixing slot plate 48 is fixedly connected to the top of the fixing mechanism 4. The fixing slot plate 48 is adapted to place the laser lamp 36. Rotating assembly 42 includes a gear 421. The rotation of gear 421 drives the sliding of a lower sliding gear shaft 424 and an upper sliding gear shaft 425. A connecting rod 422 is fixedly connected inside gear 421. The connecting rod 422 transmits the rotational force of a rotary switch 423 to gear 421. The rotary switch 423 is fixedly connected to the outer wall of the connecting rod 422. The rotary switch 423 allows the operator to control the start and stop of the assembly. The lower sliding gear shaft 424 is slidably connected inside the fixed block 41. The lower sliding gear shaft 424 meshes with gear 421 and pushes one side. The rotating rod 43 is internally slidably connected to the upper sliding gear shaft 425 of the fixed block 41. The upper sliding gear shaft 425 meshes with the gear 421 and pushes the rotating rod 43 on the other side. The self-locking component 46 includes a fixed block 461. The fixed block 461 retracts and resets to achieve clamping and loosening. The outer wall of the fixed block 461 is slidably connected to a spring 462. After the spring 462 is compressed, it pushes the fixed block 461 to reset. The outer wall of the fixed block 461 is fixedly connected to a limiting block 463. The limiting block 463 limits the stroke and cooperates with the spring 462 to self-lock. Specifically, rotating the rotary switch 423 drives the connecting rod 422 to rotate, which in turn drives the gear 421 to rotate within the fixed block 41. The gear 421 drives the lower sliding gear shaft 424 and the upper sliding gear shaft 425 to slide into the fixed block 41, pushing the rotating rods 43 on both sides to rotate along the fixed recess 44. This causes the fixed recess 44 to move, causing the fixed locking block 461 to retract. The space in the fixed slot plate 48 expands, allowing the laser lamp 36 to be inserted. After releasing the rotary switch 423, the limit block 463 and the spring 462 cooperate to self-lock the locking block 461, thus fixing the laser lamp 36. The process ensures stable transmission and improves the efficiency of assembly and disassembly. Reference Figure 1 and Figure 3 The magnetic attraction mechanism 3 includes an electromagnet 31, which generates an attractive force when energized to stably attract the track 2. A fixing clamp 32 is fixedly connected to the top of the electromagnet 31, which connects various components to ensure fixed position. A rail clamp 33 is fixedly connected to the outer wall of the fixing clamp 32, which fits against the track 2 to enhance stability and prevent lateral displacement. A manual rotating slide 34 is rotatably connected to the top of the fixing clamp 32, which rotates around a vertical axis to adjust the horizontal angle of the laser lamp 36. A manual angle slide 35 is rotatably connected to the top of the manual rotating slide 34, which rotates around a horizontal axis to adjust the vertical angle of the laser lamp 36. The laser lamp 36 is slidably connected to the outer wall of the fixed slot plate 48, which emits a reference laser beam. An electromagnetic switch 37 is rotatably connected to the outer wall of the electromagnet 31, which controls the on / off state of the electromagnet 31.

[0013] The outer wall of the fixed block 461 is slidably connected to the protective shell 47. The protective shell 47 guides the fixed block 461 to extend and retract linearly. The outer wall of the spring 462 is fixed to the protective shell 47. The protective shell 47 supports the spring 462 to exert force stably. The outer wall of the gear 421 is rotatably connected to the fixed block 41. The fixed block 41 supports the gear 421 to rotate smoothly. The connecting rod 422 is rotatably connected to the fixed block 41. The fixed block 41 limits the connecting rod 422 to transmit torque stably. The rotary switch 423 is rotatably connected to the outer wall of the fixed block 41. The fixed block 41 supports the rotary switch 423 for easy operation. Specifically, when electromagnetic switch 37 is closed, electromagnet 31 is energized and works with rail clamp 33 to firmly attach rail 2. The manual rotating slide 34 and manual angle slide 35 are rotated to adjust the angle of laser lamp 36 so that the laser is accurately aligned with moving target 5 and target target 6. Fixed block 461 slides within protective shell 47, spring 462 provides reset force, rotating component 42 provides stable transmission, and rotating switch 423 facilitates operation. The cooperation of all components achieves stable adsorption of the device, precise positioning and rapid fixation of laser lamp 36, and ensures accurate measurement of the high and low track directions of rail 2.

[0014] The implementation principle of this application embodiment is as follows: After adjusting the position, the rotary switch 423 is rotated, which drives the connecting rod 422, and then drives the gear 421 to rotate through the connecting rod 422. When the gear 421 rotates, it drives the lower sliding gear shaft 424 and the upper sliding gear shaft 425 on the upper and lower sides to slide into the fixed block 41. The sliding of the lower sliding gear shaft 424 and the upper sliding gear shaft 425 respectively drives the rotating rod 43 on both sides to move. Under the fixing action of the rotating rod 45, the rotating rod 43 rotates along the inner wall of the fixed concave block 44, thereby driving the fixed concave block 44 to move. When the fixed concave block 44 moves, it drives the fixed locking blocks 461 on both sides to retract, so that the space above the fixed slot plate 48 expands. At this time, the laser lamp 36 can be placed. After the laser lamp 36 is placed, the rotary switch 423 is slowly released. By cooperating with the limiting block 463 fixed to the outer wall of the fixing block 461 and the spring 462 fixed to the outer wall of the protective shell 47, the fixing block 461 is self-locked, and the laser light 36 is finally fixed.
